Expandable Ads

Advertisers use expandable rich media formats to expand an ad creative into a larger creative upon a user mouse-over or click interaction. The most common implementations expand leaderboard creatives vertically into larger rectangles (i.e. expand from a 90 pixel height to a 500 pixel height) or expand 250x300 rectangle creatives horizontally into larger rectangles (i.e. expand from a 300 pixel width to a 600 pixel width). Many other implementations are also possible with the expandable ad format.

Benefits of Expandable Ads

• Provide more ad space to share interactive experiences and information with the advertiser's audience.
• Support the inclusion of any number of rich media features, including video within a single ad unit.
• Allow advertisers to measure the number of ad expansions and the amount of time the ad is expanded, in addition to common measurements included in all Mediaplex rich media ad formats.
